Containers with tamper indicative hatch for sample removal

ABSTRACT

Disposable containers with a tamper indicative hatch for sample removal, methods of manufacturing and using the same are described; the containers are configured with a closure essentially obstructing the hatch, so that upon opening the hatch, the container bears a visually apparent indication that the closure has been subjected to tampering and opening.

TECHNICAL FIELD

In general, the present invention pertains to the art of transportation. In particular, the invention relates to disposable containers including a tamper indicative hatch configured for sample removal.

BACKGROUND ART

It is believed that the current state of the art is represented by the following patent literature: U.S. Pat. Nos. 2,054,785, 537,026, 5,542,598, 7,340,995, US2013146602, US2015197374, US2016039598, EP2698322, GB2489326, GB1324670 and WO2014176292.

It is often desirable to randomly sample a fruit while it is in boxes or crates that are frequently stacked several layers high in ripening rooms or cargo shipment containers. Corrugated boxes and disposable plastic containers are typically cut open for sampling, using a knife. Such a procedure commonly used in the art is potentially damaging for the fruit and may lead to unnecessary contributing to further box failure and fruit damage. Conventional plastic containers, known in the art, however, do not have a non-destructive means for fruit sampling when crates are stacked.

US2016039598 and WO2014176292 which are believed to be the closest prior art teach a collapsible, reusable plastic container that can be used for the storage and transportation of produce. The container according to US2016039598 may also have a sample door with a clip for easy access to the produce contained in the container when it is stacked among other containers. The sample door of US2016039598 provides fruit graders with access to fruit in every crate on a pallet without de-stacking. The access door in US2016039598 can be opened and closed repeatedly throughout the life of the crate without affecting the structural integrity of the crate, the protection of the fruit (e.g., bananas) or produce in the crate, or the life of the crate.

SUMMARY OF THE INVENTION

There are provided in accordance with some embodiments of the present invention, typically disposable, containers with a tamper indicative hatch configured for sample removal.

It is an objective of the present invention to provide a container with a tamper indicative hatch configured for sample removal.

It is another objective of the present invention to facilitate convenient sample removal from selected containers, while containers are stacked-up in several layers on the pallet, for instance in ripening rooms or cargo shipment containers.

It is another objective of the present invention to provide a tamper indicative hatch for sample removal, so that upon removal of a sample from the container, the container will bear an indication that the sample removal hatch has been opened.

In order to address the aforementioned objectives, the container of the invention is provided with a hatch door surrounded by perforation. The hatch door is permanently connected to the container by a bendable hinge portion as well as by a plurality of cleavable tamper indicative interconnectors.

The hatch door of the invention, surrounded by perforation and connected to the container by a plurality of cleavable tamper indicative interconnectors, facilitates convenient sample removal mechanism from the containers, as well as sustains readily apparent tamper indication that the container's door has been opened.

DETAILED DISCLOSURE OF EMBODIMENTS

Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

To depict a hatch for sample removal known in the art, reference is now made to FIG. 1, showing wall 10 of the container disclosed in a more detail in US2016039598 and WO2014176292, notably without tamper indication capabilities. Wall 10 with hinge 16 has an opening in which a door 12 is mounted in such a way that does not cut through the perimeter of wall 10. Such door 12 constructed from the same material as wall 10 is hingeably mounted or attached to the opening to allow the door 12 to pivot and be opened and closed. Opening the door 12 permits visual inspection and/or sampling of the product in the container, even when the container is within a stack of other containers on a pallet. The door 12 can be closed again, renewing the protective barrier that wall 10 to the contents of the container in storage or transport. Optionally, when door 12 is in the closed position, door 12 is coupled or attached to wall 10 by a clip 14 that prevents the door 12 from opening without user action.

The opening and door 12 in wall 10 and clip 14 having the form of a spring tang. The curved fruit sampling door 12 incorporates clip 14 that, when engaged, holds the door 12 closed and when disengaged allows door 12 to open to provide access to the contents of the container. Optionally, the clip 14 is a “low profile spring tang” mechanism which fits within the thickness of wall 10, not extending inside the curved surface of wall 10 or outside the plane as defined by the outside surface of wall 10. The mechanism of the clip 14 is reusable, allowing for repeated opening and closing of the sample door 12. The clip 14 is rotated outward to disengage clip 14 and allow door 12 to open. Door 12 and clip 14 are rotated inward with slight pressure to engage clip 14 and the latch bracket (not shown). Because of the door's 12 material, its hinged connection 18 and the use of clip 14 to secure it, the door 12 can be opened and closed repeatedly throughout the life of the container without affecting the structural integrity of the container, the protection of the product in the container or the life of the container.

In accordance with some preferred embodiments of the present invention, reference is now made to FIG. 2A to 2C, showing disposable container 20.
